This invention relates to a suction device for gasoline enginescharacterized by the feature that a vane wheel is rotatably journaledwithin the suction passage between the carburettor and the intakemanifold, at right angles to'the direction gas mixture may bepassedmanifold while being subaction of the vane wheel.

of suction, so that the up into the exhaust 'jected to the beating Thisinvention has suction device wherein the gas may be superatomized underwheel, and also air, so that anideally complete combustion of the gasmixture is made possible by a very simple 'means.

' Further objects of the invention are to economize the fuel oil; tooffer a method by which a low rade of fuel can be used effectively,without reducing the engine efliciency; and finally to substantiallyincrease the engine efficiency.

Due to the complete combustion as'realized by the invention the exhaustgas is colourless, and

odourless, and further is'free from carbon particles being deposited ontheignition plug.

Petroleum or neutral oil, as well known, contains more heat units thangasoline, but they have,

not been used as fuels for. gasolineengines, because of the badcondition in which they are brought to a combustion. Further it may beinsisted that even gasoline can not be brought to a complete combustionbyemploying the heretofore known devices. This is because of the factthat such technical advance has not yet been made by which the fuelgenerally, regardless of its quality or grade, maybe completely burned;and further difficulties are found in admixing the fuel with air. 7 I

These difiiculties' are avoided by the invention.

According to the invention, a fuel of high grade,

viz. gasoline can be more effectively vaporized than heretofore, and atthe same time can be ideally admixed with air. According to theinvention, a fuel of low grade, such as petroleum or neutral oil, can beeasily vaporized, and it is therefore made possible to use such low.grade fuels instead of gasoline, or' in admixture with gasoline.Consequently, amaterial economy of fuel expense is obtained.

The invention essentially consists in that the gas discharged from thecarburettor can be superatomized andjblended with air completely.

Referring to the accompanying drawing, illustrating several embodimentsof the invention, Fig. 1 is a front view, with parts broken off, of thesuction device made in accordance with the invention; Fig. 2 shows in asection on the line 2-2 of Fig. 1; Fig. 3 is'a-perspective view of thevane wheel.

There is arranged between the carburettor and for its object to providea the beating action of the vane. may be completely blended with thesuction pipe 2, a vane wheel casing 9 provided with a lateral wallbulged outwardly, and in the 1 interior of the casing the vane wheel ,5is journaled eccentrically to the suction passage and also at rightangles to the direction of suctiona. The vane wheel 5 is subjected tothe suction from the cylinder of the engine and is set in selfrotatingmotion. The number of revolutions of the vane wheel is proportional tothe suction capacity compared to the cylinder stroke. An

I experiment has been Chevrolet car engine with six cylinders and with3390 c. 0. cylinder volume. The result is shown in the following table:

Revolutions Revolutions per minute per minute of crank shaft of vanewheel Minimum speed working. t 200 '2, 800- 5, 300 Maximum speed working1, 500 21, 00040, 000

The diameter of the vane the experiment is two inches.

In this construction the gas pressure is exerted uponthe vane wheel onone of its lateral sides only, making it possible to increase number ofrevolutions of the vane wheel, and consequently to further make activethe beating action of the vane. i Y

In 'Fig. 3 is'shown the vane wheel which is "composed of alternate fiatperforated and im-" perforated blades 4" and 4 for the purpose of thewheel, the gas deflecting the gas in passing after passing'through theperforated blades l is deflected: by impinging upon the next imperfor--ated blade 4".
